Mars

WASHINGTON — The moon may be the next space destination for American astronauts, but the frontier of Mars still beckons, NASA chief Jim Bridenstine says.

After suffering a couple technical glitches that have put NASA's Curiosity rover off its duties on Mars this year, the robotic explorer seems to be back in full health, having driven to a new site and drilled a sampling hole, according to NASA statements.

Scientists have picked the landing site of a robot mission to Mars which will search for signs of alien life.

A new life-support system that can recycle breathable air is being installed at the International Space Station, promising to dramatically decrease the amount of water that needs to be brought to the orbital outpost to make oxygen.

Sometimes, boring is best — and that's certainly true when you're trying to set a lander down on the surface of Mars, where any eventfulness is likely bad news.

Starman has put a lot of miles on his Tesla Roadster in the last nine months.

NASA has enjoyed a nice run of Mars-landing success lately, but that doesn't mean the agency is getting cocky ahead of next month's touchdown of its $850 million InSight mission .

NASA is preparing technology for use on its Mars 2020 rover mission, due to land on the Red Planet in February 2021 — and it's breaking world records along the way.

Although Mars' atmosphere is comprised of vastly different elements than Earth's and is approximately 100 times less dense than our own, the planet does have clouds. But one strange, curious cloud over near a massive volcano is puzzling onlookers and even inciting conspiracy theories about what may be hiding below.

Earlier this week, NASA's Jet Propulsion Laboratory posted a video of how its InSight lander, set to arrive on Mars on November 26, will use its robotic arm and position its sensitive instruments on Mars' surface in an effort to study the inside of the planet for the first time ever.
